Quieter week on the big-news front. You've got Daniel Schwarz digging into `corner-shape`, Zell Liew on cascade layers with Tailwind utilities, Steve Frenzel on when `aria-expanded` belongs, plus Resurf and April UI for Laravel. Also two small tool ships: fluttersdk/wind and a new Expo ESLint plugin called panelwind. Let's dive in 👇 ## **🌟 Community News** [![](https://tailwindweekly.com/content/images/2026/09/screenshot-1440x900-1789774344428.webp)](https://github.com/fluttersdk/wind/?ref=tailwindweekly.com) ### [fluttersdk/wind](https://github.com/fluttersdk/wind/?ref=tailwindweekly.com) `wind` is Tailwind-style utilities for Flutter (Nativewind-adjacent): classes like `flex`, `p-4`, `dark:bg-gray-800` compose into widget trees, with W-prefix widgets for forms. ### [panel-ui/panelwind](https://github.com/panel-ui/panelwind?ref=tailwindweekly.com) `panelwind` is a new agent-first ESLint plugin for Expo design systems (Nativewind / Uniwind). It reads your theme, components, and variants, and knows what a class does on a device. ### [Mailviews](https://mailviews.com/?ref=tailwindweekly.com) [Cosmin Popovici](https://x.com/cossssmin?ref=tailwindweekly.com) shipped a big Mailviews update on a Friday. MCP, React Email, a new template kit and components, team invites, and a pricing refresh, with everything bumped to Maizzle 6\. Existing one-time purchase accounts get the new stuff. Official announcement lands next week. ## **🤩 Windy Picks** [![](https://tailwindweekly.com/content/images/2026/09/windy-getapi.png)](https://setapp.sjv.io/21d6nz?ref=tailwindweekly.com) ### [GetAPI](https://setapp.sjv.io/21d6nz?ref=tailwindweekly.com) — dead simple REST client on Mac GetAPI is a native macOS HTTP client from the TablePlus and Proxyman folks. Import from Postman, Insomnia, or cURL, send REST and WebSocket requests, and keep work on your filesystem with no cloud account. Autocomplete for headers and params, Apple Silicon, macOS 11+. I pull it from Setapp next to TablePlus. If you already subscribe, it is one click. If not, the trial covers GetAPI plus the rest of the catalog.

Daniel Schwarz on CSS-Tricks covers the new `corner-shape` property, which only works paired with `border-radius`. `corner-shape: bevel` plus `border-bottom-right-radius: 16px` snips a corner. Chrome 139+ for now, and borders on these shapes can look softer than you planned. ### [Using CSS Cascade Layers With Tailwind Utilities](https://css-tricks.com/using-css-cascade-layers-with-tailwind-utilities/?ref=tailwindweekly.com) Tailwind ships cascade layers (`theme`, `base`, `components`, `utilities`), and they change who wins when you mix utilities with your own CSS. Zell Liew on CSS-Tricks shows the default: park components in `@layer components` so utilities win on `class="component p-4"`. His other path puts hand-written CSS after utilities, then you punch through with `!p-4` when a one-off needs it. ### [Use cases for aria-expanded](https://piccalil.li/blog/use-cases-for-aria-expanded/?ref=tailwindweekly.com) `aria-expanded` keeps turning up on the accessibility audits Steve Frenzel runs, and picking the right pattern is the hard part. On Piccalilli he shows when it belongs on collapsible UI. Native `
` and `` cover a single disclosure without ARIA; accordions you build yourself still need the attribute. Treat APG examples as proofs of concept, not drop-in production code. ## **💅 Showcase** [![](https://tailwindweekly.com/content/images/2026/09/showcase-resurf.png)](https://resurf.so/?ref=tailwindweekly.com) ### [Resurf](https://resurf.so/?ref=tailwindweekly.com) Resurf is a personal context library that keeps notes, links, images, and documents on your device. Capture from Mac, Chrome, and iPhone into one library, organize with spaces and tags, then search or hand the context to your own AI key, MCP, or the Mac CLI. Native Swift on Mac, iPhone, and iPad. Data stays on-device, with optional private iCloud sync and no Resurf account. ## **🎁 Resource** [![](https://tailwindweekly.com/content/images/2026/09/resource-aprilui.png)](https://aprilui.dev/?ref=tailwindweekly.com) ### [April UI](https://aprilui.dev/?ref=tailwindweekly.com) If you want shadcn-style components in Laravel without leaving Blade, April UI is a free MIT kit for Blade and Livewire. Install with Composer, render pieces like button, dialog, sheet, data table, and sidebar, and keep package views in `vendor/` until you `php artisan april:publish` the ones you need to own. Alpine handles browser bits, Livewire handles server state, or mix both. Flux is the polished Livewire UI bar; April is package-first, with docs and blocks for dashboards, auth, and pricing screens. ## **👌 Cool Stuff** [**Windybase**](https://windybase.com/?ref=tailwindweekly.com) – Explore weekly curated free & premium Tailwind templates, components, and tools to help you build modern websites and apps fast.
